[%CFEngine_function_prototype(regex, list)%]
Description: Return whether any element of list matches the
[Unanchored][unanchored] regular expression regex.
[This function can accept many types of data parameters.][Functions#collecting functions]
[%CFEngine_function_attributes(regex, list)%]
some() will return as soon as any element matches.
It's convenient to set a class to not => some(".*", mylist) in order
to check if mylist is empty. Since some() returns as soon as
possible, that is better than using length() or every() or
none() which must traverse the entire list.
Example:
[%CFEngine_include_snippet(some.cf, #+begin_src cfengine3, .*end_src)%]
Output:
[%CFEngine_include_snippet(some.cf, #+begin_src\s+example_output\s*, .*end_src)%]
History: The [collecting function][Functions#collecting functions] behavior was added in 3.9.
